德國 EFBe 的車架測試

先秀一個1997年10月的報告

The results in detail: The test divides in two halves. First 100,000 cycles at a 1.200 N load are to be completed. Then the force is increased to 1.300 N and the frames are subjected to 100,000 additional cycles. As soon as the computer registers larger breaks, the test is terminated. It is important to note that the damage potential of the second level is clearly larger than that the first level. A frame that completes both levels is therefore substantially better than one which breaks after 100.000 cycles. However, altogether the racing frames show high efficiency. Compared with "simple" leisure bikes, all frames tested have a good standvermoegen. Three particularly light frames are very good: Cannondale, Principia and Trek passed through the test without breaking: the machine was stopped.

神奇夜市"奈米膠"

我是看到跟下面這位仁兄一樣的拖鞋才起了用用看的念頭:
http://tw.myblog.yahoo.com/jw!vBOoy8OYEh_cgJkcfu6l/article?mid=864&prev=887&next=827
我有很多好外胎都破損嚴重但其實騎沒多久, 所以我想用這個"可以維持彈性的三秒膠"試試看能不能修復, 一條 Schwalbe, 一條穩得勝 open胎都補好了, 後來我想如果貴森森的管胎也能補那有多好!

鬍子跟阿傑友情贊助一條騎沒50km就要丟掉的的Tufo S33pro, 兩個破洞依照店老闆指示壓合20秒, 接下來先打80psi -- 1hr過了沒事, 再打到120psi -- 2hr過了也沒事, 這時候我狠下心打到160(打氣筒的極限了) 也沒事!!

接下來是路測了, 但是我真的很想跟所有車友分享這個好用的東西, 以後騎管胎出去不用怕了, 帶一罐奈米膠起碼可以讓你撐回家

閃電牌作的"扭力硬度-重量測試"比較


"扭力硬度-重量測試"代表車架在實際騎乘轉彎及高速騎乘中對於車手踩踏的反應,數字越高,代表車架硬度越高。不過可惜的是測試對手都是2009的車款。

今年的SL3比前一代SL2輕了1百多克,強度並加強了18%!SL3的強度124, 估計SL2換算下來應該是105, 落在該表的第3名...S牌應該把自家SL2也放進來, 表示一下自家的09年技術樂勝他牌...

2008輪組超級大測試

第一項 空氣動力學 測試是在 風洞裡進行的, 由於是前輪破風較多, 所以只有測前輪,
數據是取在風速 50km/hr 之下, 輪子從左邊35度, 轉到右邊35度, 前輪所吸收的力量(瓦數) 的平均值 (越低越好)

全碳纖產品重量限制

一直以來也沒特別注意碳纖產品的重量限制, 直到公司最近從easton來了新工程師Manning我才知道EC90就算有CNT製程, 重量限制仍是160lb (等於72.57kg)

依我的超重看來, 以後自家用碳纖零件要慎選啊, 有妻小的人了...

(4/21追加)Rolf Prima TdF38 Carbon 碳纖星芒管胎輪組


藍斯阿姆斯壯 用過的知名一級輪組,
超輕 實秤前輪450g後輪620g 總重僅1070g, 輪圈高度38mm, 重量輕且風阻小 爬山賽計時賽利器

DT Aerolite 頂級扁鋼絲(一支就要150元)
前輪14支鋼絲 後輪16支鋼絲 美國鷹花鼓
每一花鼓的鋼絲孔都有加置DT銅環(詳如第二,三張照片)
藉由均攤受力面積增加鋼絲彎頭的剪力強度
這是高檔手編輪組才會有的做法

另外, 這組輪組的最大特色是他的輪框剛性(stiffness)非常佳,
因此雖然鋼絲很少, 但是輪圈上任一點受力時會由所有鋼絲分攤反力, 騎起來剛性佳

請注意:本組輪組限重150磅 (約68kg) ...Shit! 只有瘦子能騎...

《影片》

The Flying Scotsman 疾速追風(2006)

故事大綱:蘇格蘭業餘自行車好手葛蘭•歐伯利(Graeme Obree),憑著對自行車的執著,從洗衣機得到啟發,自行製造「老忠實」自行車,並且以革命性的騎姿,打破義大利自行車名家莫瑟(Francesco Moser)保持近十年的「一小時紀錄」,並克服憂鬱的心理障礙,奪下場地世界錦標賽 4 公里追逐賽金牌。

【疾速追風 The Flying Scotsman】並未在院線上映,但已經可以在錄影帶店租到DVD。本片,表面上是描述一位數次奪冠及破紀錄的世界級自由車選手心路歷程,其實骨子裡是 在問~有了名(利)以後,是否就能從此過著幸福快樂的日子?功成名就之後,是不是所有的問題都能迎刃而解?

  首先,我們來問問,為什麼走上"成名"(如影星、歌星、運動員、政治人物 等等)這條路?相信,很多人都會毫不猶豫地說是因為興趣、喜好;不過,當從小就立志當歌星或運動明星之類的(想想我們自己小時候的志願,會是不變的嗎), 真的是個人興趣?還是,父母師長在望子成龍望女成鳳的推波助瀾?有沒有小小心靈因為被光鮮亮麗、粉絲簇擁的藝人、明星所吸引、迷惑,而產生"有為者亦若 是"的虛榮心態?另外,會不會因為當代、當地正在風行某種"運動",在難逃"大時代"潮流的情況下,玩著玩著不知不覺就"習慣"玩到了成年?甚至,是被父 母師長或其他人所"逼迫",以為成名就能解決所有的問題?


  像本片男主角葛雷姆‧歐布雷,他之所以能成為英國自行車一小時紀錄保持人,是因為(白斯特牧師問他:你是怎樣喜歡上自行車的?葛雷 姆回說:)跟其他小孩一樣、有一年聖誕節得到一部單車;而他父親之所以給他這份聖誕禮物,是因為看他老是被學校同學欺負、而又不願講出那些欺負他的同學是 誰,因此在給他禮物的同時,說道:「這(單車)應該可以保護你」;果然,葛雷姆利用單車快速逃離想再次圍堵他的那些人。就這樣,葛雷姆"踏"出了他的世 界!
  英國自行車一小時紀錄保持人(想想那些參加"星光大道"歌唱比賽出線的歌手、以及那些在台灣運動會上破紀錄者),很了不起了吧,(同事兼 朋友的茂奇‧麥高文問道:你)已經是個名人,為何還來當(單車)快遞?葛雷姆回說:我像其他人一樣,還是需要混口飯吃吧!


  看到沒有!?有點(小)名氣了,卻還要為基本生活傷腦筋,這叫已有妻小的葛雷姆 如何"安"心?或許是名氣還不夠大吧!?於是,葛雷姆想向法蘭西斯‧柯‧摩瑟已保持了九年的一小時"世界"紀錄挑戰!葛雷姆要茂奇當他的經理、幫他籌募租 用符合世界標準的賽車場等等破紀錄所須經費,而他自己負責打造比賽用自行車(如採用滑雪選手合乎空氣力學的蹲姿、改良手把,將他老婆那每分鐘旋轉1200 次的洗衣機拆下來、當車輪轉軸)和苦練快速腳力。
  向世界紀錄挑戰,為了什麼?葛雷姆妻子小安就問他:「你覺得我們這樣做好嗎?向紀錄挑戰?」 葛雷姆:「當然,有什麼不好?」小安:「即使最近煩人的事很多,我們過得還不錯,我不希望破壞這一切!」葛雷姆:「不會破壞任何事情,我會好好處理,我保 證!」


  結果,葛雷姆自己打造的自行 車,有點像"怪胎",試車後,茂奇對葛雷姆說:「(另一個想破紀錄者)博德曼的自行車,花五十萬英鎊開發,由電腦設計的,(而你自造的)那東西是堆破銅爛 鐵!」(此時,連路過的孩子,看到葛雷姆自造的單車,都笑說"是馬戲團嗎")葛雷姆回應茂奇:「這輛車是依據物理法則造的,其中每一項設計都符合科學原 理,無論有沒有你,我都要打破紀錄!」

   葛雷姆總以為,他不需要誰的幫忙,他自己就能做得到破紀錄。其實,若沒有他老婆的容忍(葛雷姆只練習不工作,小安得去醫院兼職;還有,葛雷姆說都沒說就 拆了小安的洗衣機);以及茂奇鍥而不捨的募款,還找了世界級自行車匠麥克柏洛、用葛雷姆自造的那輛單車所有原理、重新打造了一輛相當流線型的比賽單車(輪 子還是"特製輪胎公司"做的);葛雷姆又如何能到挪威的哈瑪爾體育館,打破世界紀錄?

  打破世界紀錄的葛雷姆,在慶功宴上,卻獨自坐在偏遠的樓梯上心事重重;打破世界紀 錄,卻絲毫不高興,為什麼?知道這勝利並不是單靠自己可得?還是,即使破了世界紀錄,也不代表什麼?若不代表什麼,為何你一回到英國,即在麥克柏洛打造的 那輛單車,寫上"葛雷姆‧歐布雷設計與製造"?或許,是你心中早已隱隱知情,這個所謂的世界紀錄,很快就會有人來打破(沒錯,幾天後,葛雷姆所創的紀錄, 又被博德曼給打破了)!

  那麼,千辛萬 苦打破世界紀錄,除了獎金(若有的話)能讓家人實質好過一陣,以及滿足一下自己短暫的成就感、虛榮心外,為了什麼?又能給世人帶來什麼好處?讓您成為這個 地方的"XX之光"(能"光"多久?紀錄不是馬上又給破了嗎)?那這地方上的人,行走世界各地時,是不是報上您的大名,即可吃香喝辣或享有折扣優待?還是 能讓這地方之人,在國外走路都有風(若要靠別人才能肯定自己,那也是很悲哀)?您,實際上也不是這地方訓練出來的,他們沾什麼光?XX之光,或許也只是" 喊爽"的吧!?好,若說您可以給地方上的後輩,一個"學習"好榜樣;但您確定,您為了爬到世界頂端,強撐苦忍的(如片中引述曾經也是一小時世界紀錄保持人 艾迪‧莫克斯的話~這樣連續快速踩一小時單車,讓他折壽三年,他絕不再那樣折磨自己了),不會受傷(不止肉體,還包括心靈)?

  因此,電影接著安排葛雷姆因為單車爆胎,不但回到他小時候常被圍堵欺負的地方、 且又遇到那幾個欺負他的人,帶頭的那個對葛雷姆說:「你回來這裡幹嘛,冠軍?回來炫耀,對吧?」葛雷姆:「你們到底想幹嘛?」帶頭的說:「看,是他!他以 為他現在很跩了,但我還記得我們以前怎麼對待他。」‧‧‧葛雷姆:「知道嗎?你們好好看著我,除了我以外,你們再也看不到什麼了不起的人了!」(喔,如此 說來,您"成名",不是為了榮耀神、祖先或者地方,而是為彰顯您自個,好讓別人看得起您)

  為了繼續當那個"了不起"的人,葛雷姆想參加他不擅長的四公里疾速競賽,而且只剩 五星期;不過,葛雷姆依然發揮他那強撐苦忍的精神,再次刷新世界紀錄。而且,一如前次破世界紀錄,他又一個人躲了起來"沉思"(這次是在旅館房間裡);但 這次在茂奇"拍醒"他後,他對茂奇說道:「我有時候會很沮喪,然後~我會告訴自己"振作一點",然後我就不再那麼沮喪。」

  前面我們說了,葛雷姆"成名"(破世界紀錄),只是為了讓人家(尤其是那幾個小 時候欺負他的人)看得起他,好讓他能為小時候那個受盡欺侮、委屈的心靈"平反"。然而,葛雷姆只顧著要為"過去"平反,卻忽略了他因為樹大招風,受盛名之 累,"現實"上有人(戲中的代表為世界自行車聯盟)看不過眼,想盡辦法要刁難他。他沒想到,即使已成為世界冠軍,人家一樣會討厭他,一樣會要他屈服!

  對於世界自行車聯盟的百般刁難,茂奇想盡辦法也要讓葛雷姆參賽,無奈葛雷姆固執 地道:「不論輸贏,我都要用自己的方式!」結果當然是,葛雷姆被判違規、慘遭淘汰!(小時候,你鬥不過眾人--欺負他的那幾個人;現在,你仍鬥不過眾人 --世界自行車聯盟裡的那些人)

  就在 葛雷姆於家裡一遍又一遍重複看著電視重播他被判違規淘汰(接著人車摔在跑道上)的畫面之時,小時候欺負他的那位帶頭者來敲他家的門,葛雷姆不敢應門,帶頭 者趴了下來,從投信口向裡面說:「我大老遠來看你,你回來有一陣子了吧?大個子,我在電視上看到你跌倒。你知道我爸又坐牢了嗎?‧‧‧他在牢裡死了,他受 不了!你倒是很厲害,出名了,是吧?我看到你躲在那裡,你就會躲、就會跑,小王八蛋,想跑,你還覺得你比我們強,你只會騎著自行車跑掉,對不對?跑掉!難 怪你是冠軍,都是被我們逼的‧‧‧但你其實不是英雄,對吧?你這個小王八蛋,你是個飯桶,老兄,你還以為你比我們強,你什麼都不是,你真可悲!」這些話, 句句打中葛雷姆的要害,不但使得葛雷姆早已泣不成聲,並讓葛雷姆精神崩潰、扛著自行車跑到樹林裡上吊,所幸繩子斷裂、救了他一命。

  大難不死的葛雷姆,並沒有把帶頭者的話聽進去,在他妻子小安向他說"你有事,你 需要人幫忙"時,仍舊回道:「嘿,我可是個前世界冠軍,我用自己的時間,自己處理!」氣得小安說完"那你這樣寫在墓碑上吧"後,掉頭就走。

  一直在助人的白斯特牧師,找了一個與葛雷姆談話的機會,他告訴葛雷姆:「我太太 是淹死的,不是意外,她水性很好,她自殺了!她的病跟你一樣‧‧‧而且她知道沒有人能救她,因為根本沒有人知道她陷在哪裡,她的童年生活中有些事情不肯說 出來‧‧‧」葛雷姆:「你說這些有什麼用?」白斯特:「你以前談過這些事嗎?(葛雷姆搖頭)那你怎麼知道沒有用?」葛雷姆:「他們讓我覺得我很沒用,好 像~好像我一無是處,只會被人~利用!」白斯特:「"他們"是誰,葛雷姆?沒關係,這就像~就像你第一次騎自行車,繼續騎,就沒事了!」

  凡事起頭難,既然找出葛雷姆的病因,接著葛雷姆又肯開口主動要小安幫他在醫院找 個專業的心理治療師,即表示葛雷姆不再用追求冠軍或破紀錄(讓人看得起)的方式,來撫平舒解他過去鬱抑的心結;因此,他不再像以前一樣,只參加破世界紀錄 的大賽,他也願意參加一些小型比賽、試試身手;還有,他在比賽場上,也不再專斷獨行,願意參考茂奇給他的建議。

  另外,我想葛雷姆最後終於領悟到~名利,或者說外王事業,是需要配合天時地利人 和,並非自己獨自一人可完成;而且,得來的榮耀,應歸屬大眾(像葛雷姆在奪得1995年世界自行車冠軍後,將他原本在單車上只有"葛雷姆‧歐布雷設計與製 造",在歐布雷後+小安+茂奇+白斯特。就如同奧斯卡得獎人總會感謝很多人一般),如此一來,才能真正"名"副其實。

觀後評語:在看這部片之前,不妨先做點功課,看看我先前寫的「與風阻的對抗賽」, 裡面有提到自行車風阻與一小時世界紀錄的故事。一小時紀錄指的是在場地中連續騎一小時的車,看看騎了多少距離--也就等於平均時速。在 70 年代之前,使用傳統的彎把場地車,距離都難以突破 50 公里,並且紀錄在偉大的自行車手艾迪•墨克斯(Eddy Merckx)於 1972 年創下之後就止步了。一直到 1984 年低風阻器材的開始被使用,才由義大利計時賽好手莫瑟,把距離一舉突破 50 公里,接下來近十年內無人能突破。

接下來就是歐伯利的故事了。他不是職業車手出身,沒有像墨克斯和莫瑟一樣顯赫的成績,但他對自行車的熱情,卻是更勝這些前輩的。歐伯利不像職業車手 有贊助、有團隊、有車廠量身訂做的利器,但他有的是突發奇想的腦袋,以及隨意揮灑的空間。他以打破一小時紀錄為目標,從建造自行車架開始,希望能造出一台 兼俱低風阻和剛性的自行車。當時碳纖維複合材料的車架是主流,由於 UCI(國際自行車聯盟)規則訂定不嚴,各家廠商不計成本傾全力朝最低風阻的可能性去設計車架,也是低風阻車架的黃金時代。歐伯利沒有資金沒有支援,沒辦 法造出一流的車架,那麼就改變騎姿--這是他最天才的構想,也給僵化的職業自行車壇投下一枚震撼彈。儘管他第一個發明的騎姿旋即被禁,但他的反社會性格讓 他再創造另一個奇特的騎姿(超人姿勢),再次打破紀錄,並獲得世界錦標賽四公里追逐賽金牌,成為蘇格蘭的榮耀。

這是一部傳記電影,也有些許的勵志性質,演員雖然不有名,但已經足夠把這位傳奇人物詮釋得很好了。和職業車手比起來,歐伯利更像是平常人,沒有財力 與背景,也有懦弱害怕的時候,只因為對自行車的狂熱,讓他在自行車歷史上留下奇特又美麗的一筆。

Amarican Flyers 壯志奪標(1985)

故事大綱:一對因為雙親問題鬧彆扭的兄弟,參加一場名為「西部地獄」的自行車三站賽,在前往賽會的路上一同訓練,盡釋前嫌。做哥哥的 隱瞞了自己的病情,雖在比賽第一站取得勝利,但在第二站的比賽中腦子裡的炸彈爆開了,生命垂危,做弟弟的仍堅持比賽下去,為哥哥實現奪冠的夢想。

觀後評語:80 年代美國自行車壇的沙漠中出現了綠洲,7-Eleven 車隊剛開始參加環法賽,一直到 80 年代末雷蒙德贏得三次環法賽黃衫,沈睡的雄獅終於醒了,後續才有更多優秀的運動員投入這項運動。在這個年代拍攝的電影,劇情似乎還停留在「業餘選手」的等 級,「美蘇大戰」的腳本從軍事競賽轉移到自行車競賽上。其實稍有常識的自行車迷都知道強者不可能是蘇俄選手,但在那個時代背景下,電影要賣錢只好這樣拍 了。有在從事自行車競賽的車友,應該會發現裡面有些小細節不合常理,令人發噱。電影另一個賣點是演哥哥的是凱文科斯納,是大家比較熟悉的。偉大的自行車手 艾迪•墨克斯也有露臉為比賽鳴槍(當時真是年輕啊)。

Breaking Away(1979)

劇情大綱:一個老是幻想自己是義大利人的美國小子,對自行車賽充滿幻想。在一個小鎮舉行的自行車賽中,他竟然被受邀參加的義大利車隊 掀翻了,從此他對義大利人幻滅。後來他參加州內舉行的自行車接力大賽,和另外三名哥兒們組隊,雖然這三人只是去陪騎的,但靠著主角個人的實力,仍然打敗陣 容堅強的對手,贏得這項大賽的冠軍。

觀後評語:這是一部青春電影,描述的是小鎮的故事,雖然沒有偉大的事蹟,但年近中年的我,看完後會有一種「這就是青春啊!」的感慨。 主角幻想自己是義大利人的情節十分好笑,他那三位遊手好閒的哥兒們也不是等閒之輩,其中一位就是近年演「明天過後」的男主角。看看他年少輕狂時體格如此健 壯,再看看「明天過後」裡那位沈穩嚴肅的英雄老爸,頗有時空錯亂之感。這部片比起「壯志奪標」更值得推薦,劇情比較合理些也有趣許多,可惜台灣沒有發行, 只能看英文版。

《動畫》

茄子 I

故事大綱:PaO PaO 啤酒隊裡的副將貝貝,面臨生命中最堅難的時刻。他在環西班牙賽的一站中,將經過他想逃離的故鄉,而這一天他的前女友要嫁給他哥哥。他在無意中聽到自己將被 解職,但他仍要完成車隊賦予他的任務:幫助主將奪勝。他的心中五味雜陳,而在此時主將發生意外摔車,使得他的任務變成要贏得勝利。

觀後評語:請參考我先前寫的「茄子-安達魯西亞之夏」。你 可以從劇裡的比賽播報員學到很多職業競賽的策略和知識。劇情大致上都很合理,除了最後單飛選手在集團衝刺中勝出,這在現實比賽中是不可能發生的,倒是很多 辛苦逃脫一百公里但在在最後兩百公尺被集團併吞的案例。但我仍然十分推薦這部動畫。

茄子 II

故事大綱:一位知名車手身亡了,身為他的同鄉與好友,PaO PaO 啤酒隊的喬奇強打精神參加日本盃的比賽,與貝貝共同為車隊的主攻手。除了本身實力不足之外,還要面對明星車手、地主車手以及宿敵的挑戰。這時候,喬奇能依 靠的只有隊友的協助了。

觀後評語:第二集就像是「茄子自行車賽第二站」,劇情比較沒有像第一集一樣有深度,而且一些細節也沒有交待清楚,看到許多只演了一半 的旁枝情節,但比賽內容還是不錯的。國際重大賽事,像是世界錦標賽或者奧運會,都是採用「繞大圈」的路線,一圈約二三十公里,要跑七八圈,約兩百公里以上 的距離,帶有一些爬坡,這樣的比賽路線在台灣比較少見。因為同樣的路線繞好幾圈,第一圈過後大家心裡都有個底,第二圈開始攻勢不斷,難度很高,強度也很 高。除了體力還需要判斷力,以免太早就耗盡體力。在茄子 II 之中對這種比賽的描述還蠻考究的。本片尚未引進至台灣,想看高品質動畫的車友,麻煩請上發行商普威爾的網站幫忙連署,不要看品質不佳的網路流傳版,以免影響觀賞心情。

《漫畫》

鐵馬頑童(單行本 1-18 完)

故事大綱:野野村輝是一個看到爬坡就不認輸的熱血少年。進入高中後與隊友、外國留學生產生激烈的競爭,在幾次對決之後以環沖繩自行車 賽作為最後了斷的舞台。最終阿輝和隊友以燃燒生命的方式騎完比賽。

讀後感想:這是一部熱血漫畫,我覺得已經接近「格鬥漫畫」的程度了。而環沖繩自行車賽也確有其事,因為漫畫的關係讓這場比賽成為日、 台兩地業餘車手「朝聖」的比賽。我和小花也去比過,不妨翻翻以前的文章看我們的記錄。不過奉勸大家,這部漫畫除了熱血之外其餘的描述都是大有問題的,不論 訓練還是比賽,都帶給讀者許多錯誤的觀念,千萬別照著那種方式去練,那簡直是玩命,不搞出一身運動傷害才怪。要學正確的訓練知識,讀讀「鐵人三項訓練聖 經」才是正途。話說回來,實際上去沖繩比賽時,那些日本人不分年紀不分男女還真的是熱血到不行啊!

單車少女(單行本 1-20 未完)

故事大綱:故事都圍繞著青葉自行車行打轉,描述車店與客人之間所發生的溫馨感人的故事。都是短篇故事,每一篇的主角不盡相同,甚至出 現的腳踏車也都不同,但都發生在那間如小叮噹口袋的神奇車行裡。

讀後感想:這是一部置入性行銷的漫畫,作者除了畫感人的故事之外,也協助有創意、有理念的自行車廠介紹產品,簡直就是一部「漫畫型 錄」。雖然如此其實商業味道並不濃,反而能夠看出「讓腳踏車豐富你的人生」這樣的期許,讀起來趣味盎然。看完之後很羨慕日本人有這麼多樣化的產品可以選擇 啊!尤其是那種小孩子可以坐在菜藍裡的親子車,真是炫到不行!真想要一台。畫工可說是所有單車漫畫裡最好的,尤其是畫身村玲瓏有致的女性......

《書》

重返艷陽下

故事大綱:美國名車手藍斯•阿姆斯壯(Lance Armstrong)的傳記故事,描述他少年得志,卻罹患癌症使得人生急轉直下,又復出車壇,取得環法賽總冠軍的曲折故事。

讀後感想:阿姆斯壯的傳奇故事,十年來已經透過媒體,讓大家都深受激勵。許多人腕上會戴著「Livestrong」的黃手環,象徵的 不只是不向命運低頭的頑強生命力,更幾乎成為自行車族群的共通語言。書中除了由本人敘述更加真切之外,還有許多職業車隊在訓練、比賽時的點點滴滴,是一本 外人得以一窺職業車隊以及環法賽的勵志傳記。

鐵人三項訓練聖經

內容大綱:教你正確的訓練與比賽觀念。

讀後感想:如果你真的很有心,把以上的影片和讀物全都看完了,我想你會很迫不及待地衝出去訓練,準備在比賽時燃燒熱血。但是請等等, 以上所介紹的材料,通通都不是正確的訓練觀念喔!也許有鳳毛麟角的偏方是值得你借鏡參考的,但沒有一個提供你完整的訓練體系,甚至誤導你的訓練方向。簡單 講就是:照著練你就不妙了!不要被熱血沖昏腦袋,先冷靜一下,讀本正經的書,拿起紙筆,好好規劃你的訓練計劃。「鐵人三項訓練聖經」就是一本最好的參考 書,裡面有你所不知道的運動科學知識,更有奧運選手行之多年的訓練系統,指導你走向正軌,不被旁門左道所迷惑。前面幾項你不看不會感到可惜,但「鐵人三項 訓練聖經」是你一定要買一本來讀的啦!

車架材質vs車架壽命

Steel and titanium only fatigue if loads abnormal (possibly unheard of) for cycling are placed upon them. Where aluminum fatigues at any load level, ie. every pedal stroke contributes to the frames death. As for the "all metal frames fatigue and eventually fail" statement, that is not a realistic view to take. How long are you going to live? Steel and titanium are going to outlast you by far, and titanium will outlast your children. Ultra-violet radiation can weaken the breaking load of Carbon.

鋁材質的特性是金屬疲勞閥值超低,幾乎所有受到的應力都會累積。

相對來說,鋼材質也是會金屬疲勞,不過閥值較高,在彈性範圍內,幾乎都會回復,不太會累積應力。(所以才有人說鋼管車可以傳家!不過,保存不好,可能會鏽掉!)

至於碳纖材質,就算不疲勞,也是會直接老化(紫外線),然後就不治了。

鋁材及鋼材的金屬疲勞特性受時間影響不大,不太會自己掛掉!

Where was my bike made?

Or, who actually made my bike?

Revised March 18, 2008

Please do not paste this article into a blog, website, or email as the content may be updated from time to time. Instead, please link to this page so your reader will have the most current information. Thank you.

Kerry Roberts is the past president and chairperson of the National Bicycle Dealers Association and provides consulting services to the bicycle industry. He is also the owner of The Bicycle Company, which includes Bike Pedlar retail stores in Nashville, Brentwood, and Hermitage, Tennessee.

The information contained in this report comes primarily from Bicycle Retailer and Industry News' Factory and Suppliers Guide, published annually in October. Bicycle Retailer and Industry News is the definitive trade publication in the bicycle industry. Other sources of information include trade show and factory visits, technical writers in the cycling media, and bicycle company employees who wish to remain anonymous.

Some bike companies have a few secrets. And one of those secrets is where your bike is made or who actually made it. The bike companies like it that way because many of them rely upon the same factories to build their bikes!

The big picture is pretty clear: around 95% of the bikes sold in the U.S. are made in China or Taiwan by a handful of manufacturers of which Giant is the largest.

Generally speaking, low to mid level bikes are made in China and mid to high level bikes are made in Taiwan. The exception is carbon; many manufacturers use Chinese manufacturers to make their carbon frames – even their high-end racing frames.

When it comes to knowing where your bike is made, shouldn’t it be as easy as looking at the sticker on your bike or what is printed on the box in which your bike came? After all, how confusing can a label that says “Made in the USA” or “Made in France” or “Made in Italy” be?

W
ell – in a word – very. It is very confusing because your definition of “made in” is different from the bike industry’s definition.

A typical rule of thumb is that the country claiming origin has to add 60% or more of the value of the final product.

For example, you and I can import an unpainted carbon fiber racing frame from China to Spain which will ultimately retail for $4,000 with Shimano components in the United States.

The frame and fork may only cost $200 from the Chinese manufacturer. In Spain, we will paint, decal, assemble, and box the bike for shipping to the U.S.

Our cost to paint, decal, assemble, and box might be $300 and the cost of the components might be another $800.

So is this bike “Made in China” or “Made in Spain?” According to the bike industry's definition, the bike is made in Spain. The sticker will say “Made in Spain” as will the shipping box to the United States because over 60% of the value will be added in Spain.

Let’s say we take the same frame and have the Chinese manufacturer paint it, decal it, assemble it into a bicycle, and ship it to Spain. When we ship it to the United States, the label will have to say “Made in China.”

Perhaps the best way to eliminate the confusion is for the bicycle industry to follow the lead of the automobile industry and tell the end consumer the countries of origin of all aspects of the bicycle.

After all, if you are led to believe by a bunch of marketing people that your bike was handmade in Spain when it was actually mass-produced in a Chinese factory, would you buy that bike? Maybe – but you wouldn’t pay a premium for it.

With these things in mind, here is an alphabetical brand by brand run down of some key bike brands sold in the U.S. along with a few bits of trivia.

Bianchi - As I was writing this, it occurred to me that Bianchi and Schwinn have remarkably similar histories. Both were turn-of-the-century family-owned companies, manufactured their own bicycles, were popular brands in their respective countries, fell upon hard times, were eventually sold, moved substantially all of their production to Asia, and have seen a resurgence in the past few years under new owners!

In 1996, Bianchi was sold to a Swedish conglomerate (now known as Cycleurope1) whereas Schwinn went through several owners before winding up with Pacific in 2001.2

Under Cycleurope, which owns 11 bicycle brands,3 much of the bicycle production shifted from Italy to Asia, with the exception of some final bicycle assembly (i.e., Asian frames assembled into complete bicycles) and limited high-end production.

Let me take a minute and address Reparto Corse bicycles, because their "Made in Italy" sticker is a source of confusion.

The historic Treviglio factory - a monstrosity of a thing which used to house much of Bianchi's manufacturing before it shifted to Asia - has a section dedicated to Reparto Corse. It used to be that Reparto Corse (RC) meant the race department where high-end bikes were made. Now it is used as sort of a branding logo to identify the upper-end bikes that get the RC design and marketing treatment.

Many of the RC bikes have a "Made in Italy" sticker, which usually means assembled in Italy using a frame made in Asia. For example, the carbon RC frames are made by Advanced International Multitech (a Taiwanese carbon manufacturer of bike parts, baseball bats, golf shafts, arrows, fishing poles, etc.) and the aluminum frames are made by Taiwan Hodaka.

There are some frames still welded at Treviglio. My understanding is that the aluminum frames with carbon rears are either welded there or, at least, bonded there. I also understand that the frames with foam injection have the injection process completed there, even if the frames come from Asia.

Although Taiwan Hodaka manufacturers many of Bianchi's U.S. models, Fairly and Giant have manufactured for Bianchi in the past.

Cannondale - Aluminum Cannondales are made in the U.S. Cannondale, which was owned by founder Joe Montgomery and his son Scott. Cannondale is now owned by its key investment fund after experiencing financial problems. Cannondale's market share appears to have diminished but stabilized.

According to Bicycle Retailer and Industry News in June 2007, low-end Cannondales are made in Taiwan - probably by Fritz-jou. Others are welded and painted in Taiwan then sent to the US for assembly. The Synapse is made by Top Key.

In February 2008, Dorel Industries announced the acquisition of Cannondale and Sugoi clothing in an all-cash transaction of $190 million to $200 million. Dorel purchased Pacific Cycle (Schwinn, Mongoose, and GT Bicycle brands) in 2004.

Cervelo
- Cervelo is a Canadian company. Bikes are made in Asia and assembled in Canada.
ex. Cervelo R3 is made in China.

Colnago - In 1944, when Ernesto Colnago served as a 12-year old apprentice in the shop of Dante Fumagalli, did he have any idea he would become the most famous of all Italian frame builders?

Colnago is, perhaps, the most coveted of all professional-quality bicycle brands - just look at the pages of VeloNews or Pro Cycling and see how many professional riders race on Colnagos!

Frames are still hand-made in Italy, except for three entry level aluminum models made in Taiwan (probably by Giant) and the carbon CLX, which is also made in Taiwan.4

De Rosa - De Rosa is an Italian company that is one of the Italian "big three" that includes Colnago and Pinarello. Ugo De Rosa, along with his sons, have been building bikes for over 50 years. As far as I know, all bikes are made in Italy.

Ducati - Bianchi has announced a licensing agreement with Ducati to produce a line of bikes with the Ducati name. It is my understanding that the frames will be sourced from Asia with the final assembly at Treviglio.

Felt - Felt was started by motocross guru Jim Felt. All production comes from Asia.

Fisher - Gary Fisher is the "godfather" of mountain bikes. After struggling with his own bicycle company, he sold his brand to Trek Bicycle Company. Still involved in designing and marketing his brand, Gary is a popular figure at bicycle industry events. He's sort of a cult figure with an unmatched sense of fashion! Fisher bikes are made in Asia, except for the full-suspension rigs (which are made in Wisconsin).

Fuji - Fuji is now owned by Ideal, who manufacturers most of their bikes. Ideal is one of the key Taiwanese manufacturers along with Giant and Merida. Ideal also manufactures for other brands. Topkey of China manufacturers Fuji's carbon frames.

Giant - You may have ridden a bicycle made by Giant without knowing it! Giant is the world's largest bicycle manufacturer with factories in Taiwan, China, and Europe. Giant, a Taiwanese company started in 1972, manufacturers their own bikes - including the carbon bikes, which is unique in the industry (i.e., most other brands utilize other manufacturers such as Advanced or Martec).

In addition to making their own bikes, Giant also makes, or has made, bikes for many other prominent brands, including Trek, Specialized, Schwinn, and Bianchi. Giant's claim to fame is that they have the most sophisticated and efficient manufacturing facilities in the bicycle industry.

A bit of trivia is that Giant owns 30% of Hodaka, a key Taiwanese supplier for many brands such as Bianchi.5

Giant also sponsors the T-Mobile professional cycling team.

Haro - a California BMX company started in 1977 by Bob Haro. All production comes from Asia. Haro owns the Masi brand. Kenstone, with factories in Tawan and China, is a key supplier.

Jamis - Jamis is the house brand of G. Joannou Cycle, a long-time distributor of bicycles and accessories. The bicycles are designed in the U.S. and sourced from Asia.

Kestrel - Kestrel, an early pioneer in carbon frames, introduced the first production non-lugged carbon frame in 1986. Originally, frames were manufactured in California. In recent years, production shifted to Asia. The frames appear to be made by Martec.

Kona - a California company with all production from Asia. Kona, founded in 1988, is a very small company similar in size to Marin. Fairly and Hodaka in Taiwan are key suppliers.

Kuota - Kuota frames are made in Taiwan by Martec, the same manufacturer that makes Kestrel frames. Kuota is a creation of Sintema, an Italian manufacturer of components. Basically, they designed the frames, had the frames manufactured in Taiwan, and marketed the brand heavily in the U.S., Western Europe, and Australia. Kuota has been a successful brand launch in a very short period of time.

LeMond - Greg LeMond is the first American to win the Tour de France, winning in 1986, 1989, and 1990. LeMond also won three World Championships and the Tour DuPont. His career was cut short by lead poisoning from a hunting accident. LeMond's early bikes were made by Roberto Bilatto in Italy and distributed by a now-defunct company named Ten Speed Drive Imports. The Bilatto-made frames are somewhat collectible.

After an attempt to have an independent bike company, LeMond licensed his brand to Trek Bicycle Company.6 Trek now designs and markets his bikes, which are made in Asia except for the spine bikes featuring OCLV carbon (which are made in Wisconsin).

A bit of LeMond trivia is that he helped develop the first aerobar with Scott and used it in his amazing come-from-behind victory in the 1989 Tour de France.7

Litespeed - Starting in the 1980's, Litespeed was a pioneer in titanium frame building. As their reputation grew, a steady stream of cycling legends came to Litespeed for their titanium expertise. For many years, Litespeed built frames for famous brands such as DeRosa, Merckx, Basso, LeMond, Tommassini, and others.8

Litespeed was, for a period of time, the largest manufacturer of high-end bicycles in the world. All bikes, including the Merlin brand that they own, are made in Tennessee except for the carbon Pavia (which has been discontinued). The Quintana Roo brand is also owned by Litespeed but is made in Asia.

Look - Look is a French company with frames made in France and Asia. Look is also a leading pedal brand.

Marin - a California company with production from Asia, except for a handful of high-end models. Marin is a very small company similar in size to Kona. Key Asian suppliers are A-Pro, Fairly, and Sunrise.

Masi - Faliero Masi was, in my opinion, the "grandfather" of all Italian frame builders, serving as inspiration to famous frame builders like Ernesto Colnago. Faliero sold his company to Americans in the early 70's. Since then, the brand has had several owners including Schwinn! At present, the Masi brand is owned by Haro (the California BMX company)9 and the bikes are made in Asia.

One of my favorite frames was a made-in-Italy Nuovo Strada that I bought from Cumberland Transit in the 80's. Unfortunately, it was stolen in the 90's!

Alberto Masi, Faliero's son, still hand-makes the traditional Masi frames in the shadow of the Vigorelli Velodrome in Milan. Unfortunately, these frames - due the licensing of the Masi name to Haro - are not sold in the U.S. under the Masi name. Instead, these frames are sold in the U.S. under the "Milano" name.10


Merlin - see Litespeed.

Olmo - Olmo is a prominent brand in Italy. Traditionally, Olmo has been made in Italy. I don't have any information on whether any models are made in Asia.

Orbea - Orbea is one of the two large Spanish bicycle manufacturers. It is sort of like Spain's version of Trek or Schwinn. Bikes are produced in Spain and Asia. High-end carbon frames are made in Asia and "finished" (i.e., painted) in Spain.

From Bicycle Retailer and Industry News:

Orbea builds aluminum frames in-house. Carbon fiber frame production, which accounts for half of its road bikes, up from 20 percent just three years ago, is outsourced to such Chinese specialists as Martec.

But unlike many bike makers who are content to tweak stock factory frames, Orbea does all of its carbon fiber frame design, engineering and prototyping in-house. It builds its own molds for new frames and assembles several dozen prototypes before handing off manufacturing instructions to China.

"We need to keep and develop our own knowledge of composites and carbon fiber, and then to find someone who can work with us to build what we want them to build," Joseba Arizaga (Orbea's marketing manager) said. "We make the molds, the first frames, everything here in Orbea. Then, when we are ready to do mass production, we send the instructions to Asia." 11

Pinarello - This Italian company has been producing world-class frames since the 1950's. Pinarello - along with Colnago and DeRosa - is one of the Italian "big three." You can visit their website, pinarello.com, for a nice history of the company.

Some frames are now made in Taiwan, including the aluminum Galileo. I haven't been able to confirm this, but apparently the carbon frames are made in Asia then shipped to Italy for painting and assembly.

Raleigh - A few years ago, the U.S. management team, headed by former Murray exec Bill Austin, bought Raleigh from its U.K. owners. Headquartered in Kent, Washington, production comes from Asia, with key suppliers being Kinesis and A-Pro.

Schwinn - Schwinn was for many years the largest American brand. All bicycles were made domestically until the late 80's.

In 1985, Schwinn management called mountain bikes a "fad" - oops.12 After two bankruptcies, Schwinn is now owned by Pacific, who also owns GT, Mongoose, and the Pacific (and some other brands). Pacific is headquartered in Madison, Wisconsin.

Under Pacific's ownership, the Schwinn brand is returning to prominence. Pacific sells more bicycles than any other brand in North America. However, that includes Pacific brands sold at WalMart, Target, etc.13

The bikes sold in the U.S. are made in Asia, many by Giant.

Scott USA - Scott got its start in Sun Valley, Idaho, when Ed Scott developed the first aluminum ski pole in 1958. In the 80's, Scott developed a bike line.

Eventually, Scott pulled out of the U.S. market and focused on Europe, where Scott is headquartered.14

After an absence of several years, Scott has returned to the U.S. market under the direction of Scott Montgomery of Cannondale fame. Although the company is headquartered in Switzerland, production comes from Asia, with key suppliers being Hodaka and Giant.

Serotta - Serotta is a U.S. manufacturer of high-end bicycles. It competes with Seven and Waterford and is of similar size to Waterford.

Seven - Seven is America's number one custom bicycle brand. Seven Cycles was founded by Rob Vandermark in early 1997.

Rob, previously head of R&D at Merlin Metalworks, decided to branch out on his own and develop a company to build high-end titanium and steel frames. He also wanted to offer the rider custom geometry, without extra charges and long lead times. So Rob assembled a team of experienced craftspeople who all shared a common goal: To build the highest quality, most innovative frames, and therefore provide the cyclist with the best riding experience possible.

All bikes are hand-made in Watertown, Massachusetts.

Specialized - Started in 1974 by Mike Sinyard, Specialized has enjoyed a long-standing reputation for being a leading bicycle design and marketing company.

Several years ago, Merida (a Taiwanese manufacturer) bought a substantial interest in Specialized. Although Specialized is still headquartered in California under the leadership of founder Mike Sinyard, all bikes are made in Asia. Key Asian suppliers are Merida, Ideal, and Giant.

Time - Time produces what is arguably the most advanced carbon frame in the world and all frames are hand-made in France, even the entry level frames.

Trek - It's hard to believe that America's largest bicycle brand had humble beginnings in a barn! Yet in 1976, Dick Burke - with an investment of $25,000 - started making bicycle frames in a little red barn near Madison, Wisconsin. By 1980, Trek built their first manufacturing plant in Wisconsin and the rest, as they say, is history!15

After many years of making its own bicycles in the U.S., Trek moved entry and mid level bicycle manufacturing to Asia.

In 1992, Trek introduced its proprietary OCLV carbon process (Optimum Compaction Low Void) which is still used in its handmade carbon frames. All OCLV carbon frames - road and mountain - are still made in Waterloo, Wisconsin. The all-carbon 5000 (which does not feature OCLV) is made in Asia.

Worldwide, Trek is the second largest bicycle company after Giant (of the brands sold only in bicycle stores). They are one of the most sought-after brands by U.S. dealers because of their strong commitment to brick and mortar bicycle stores (i.e., the brand cannot be sold mail order or over the Internet) and because of their dealer-friendly policies.

Trek owns (or licenses) Fisher, LeMond, Klein, and Bontrager.

Tommasini - Tommasini is a small Italian frame builder in Grosseto, Italy, of similar size to Seven, Waterford, and Serotta. Much of Tommasini's production is exported out of Italy, with their largest markets being the U.S., Germany, and Japan. In September 2006, Irio Tommasini's nieces took over U.S. distribution and are relaunching the brand in the U.S.16

Waterford - Waterford is America's number one steel custom bicycle brand. All bikes are hand-made in Waterford, Wisconsin.

In the late 1970's, a young rider, designer and builder named Marc Muller was hired by the Schwinn Bicycle Company. He brought the experience and innovation from his own framebuilding enterprise and took charge of building the Paramounts, the dominant brand of American-build racing bicycles.

In the early 1980's, Marc moved the Paramount factory to Waterford, Wisconsin and continued building elite bicycles and also created a cycling design laboratory.

Marc and his staff introduced a number of key innovations including oversized tubing (one of the most significant advances in frame design), 26" wheels, cast-in cable guides and a patented full suspension system. These advances allowed them to design and build bikes for National and World champions such as Ned Overand, Marc Allen, Mike Engleman, Tom Prehn and many others.

In 1993, Marc Muller and Richard Schwinn, great-grandson of Ignaz Schwinn, bought the Paramount factory and renamed it Waterford Precision Cycles.17

Marc is now one of the most respected bike designers in the entire bicycle industry. And Waterford, with a one hundred year heritage in bicycle manufacturing, continues to make a winning, world class frames one at a time.

Waterford is 90 minutes north of Chicago. If you visit Chicago, feel free to call for a factory tour.

What have I missed? Let me know and I'll be happy to reply. Again, you may wish to consult Bicycle Retailer and Industry News' 2007 Factory and Suppliers Guide, published in their October 1, 2006, issue. The guide lists which factories the U.S. brands use for their manufacturing.

Custom Road Bikes

This page is updated from time to time, so please check back for the latest.

Kerry started Allanti Bicycle Company in 1990. Click here to read his blog.

Are you ever confused about what high-end bike to buy?

Throughout the 30-plus years and almost 200,000 miles of riding and racing, I've sold, assembled, or ridden almost every brand of professional frame including (in no particular order) Bianchi, Masi, Merckx, Merlin, Pegoretti, Fondriest, DeRosa, Cannondale, Guerciotti, Litespeed, LeMond, Moser, Pinarello, Klein, Colnago, Torelli, Look, Vitus, Trek, Tommasini, Waterford, Kestrel, Giordana, Seven, Time, and more!

This page contains a few of my thoughts on many of the fine professional bicycles that I've had the pleasure of building or riding.

Before we talk about brands, materials, etc., let's talk about what matters the most: fit. If the bike doesn't fit, you will miss the comfort, performance, and enjoyment that a custom road bike offers.

Getting the right fit can be a little bit confusing. Almost every bike shop employee has some fundamental knowledge of fitting, but fundamental knowledge is no substitute for extensive education and experience. Our trained specialists fit more made-to-measure frames than any other store in Tennessee (and probably the Southeast). But even with our qualifications and experience, we always double-check our work in-house and make sure our most experienced people sign off on each fit.

Second to fit is buying a bike for your intended purpose. If you want to race, buy a level of quality that will withstand the rigors of racing. If you want to tour, buy a bike that is stable under load. If you just want to ride recreationally, buy a bike that is easy to handle.

Third, buy it from someone reputable who listens and is focused solely on your needs. As the old saying goes, everyone has an opinion. But some people have better opinions than others. Make certain the person giving you advice is qualified to do so. And make certain the person selling you the bicycle will stand behind their work with a solid guarantee. Our guarantee is simple: love it or bring it back.

Next on my list is materials and last on my list is brand. All the materials are good and, at a similar price point, most brands are of similar quality. But having said that, I do have favorites - for both materials and brands.

My favorite material is steel - even though I enjoy both titanium and carbon. Steel has the ideal ride properties: laterally stiff, vertically compliant, and with just enough feedback to give you the input you need without the fatigue. Sort of like driving a BMW. And, with the advances of the past few years, steel no longer carries the weight penalty it once did. Quality steel frames often weigh less than titanium. We just built up a 64 cm Waterford (a big bike!) that weighed under 18 pounds - remarkable!

There are many, many quality steel frames, but my long-time favorite was the Moser Leader AX. Designed by the Italian cycling great himself, each Leader AX was silver fillet brazed. After some tough times, Cicli Moser - under the direction of Marco Dallapiccola - is re-establishing itself with products that capture the passion of Italian cycling products.

Speaking of Italian products, the Italian cycling industry is going through a difficult time. Since 1994, bicycle production has dropped by about half. And all of this has occurred during a growing road bike market.

Although we don't sell as many Italian bikes as we used to, the Italians are the heart and soul of the bicycle industry. We certainly hope the Italian bicycle industry will be able to recover and become the market leader it once was.(We continue to sell and believe in Colnago, the premier Italian brand of pro frames).

Fortunately, artisan-quality frames are still available - and you don't have to travel to Italy to find one! In Waterford, Wisconsin, resides a world-class producer of artisan-quality frames. Operating in the old Schwinn Paramount factory is Waterford Precision Cycles.

I can't say enough good about Richard Schwinn and his great team at Waterford, so I'll just leave it at this: I have three Waterfords - a Waterford 2200, a Waterford RSE-14 for touring/commuting, and a Waterford R-14 with S&S Couplings for travel (i.e., it comes apart and fits in a suitcase). Further, most of our staff also ride Waterfords.

We are also enamored with Seven Cycles. Seven may not be a familiar name - but you know their history! Seven is comprised of the original Merlin team. Long story short: they left to start their own company and do things the way they thought they ought to be done. The result: a brilliant custom bike in steel or titanium.

If you want a world-class product, if you need custom geometry, or if you need a special paint scheme, Waterford and Seven are it. Take a test ride on our demo bikes and I'm certain you'll agree.

Let me point out that Watefords and Sevens are truly custom-made. They are made to measure for you, with your style of riding in mind. Why buy an off-the-shelf frameset when you can have it made-to-measure for a similar price?

I might add that my Waterford 2200 with Dura Ace components, a Thomson stem and seatpost, Flite Gel Flow saddle, and standard wheels with Mavic Open Pro's weighs a little over 19 pounds. I also have the traditional steel fork (which adds over half a pound) - so figure 17 pounds with carbon fork and racing wheels. My Waterford R-14 weighs under 18 pounds even with the S&S Couplings.

For folks who want an "off the shelf" titanium of top quality, we sell Litespeed. Litespeed is the industry standard in titanium - and it may surprise you to know that they are made right here in Tennessee! I might add that Litespeed now makes custom geometry frames - so for those who need custom geometry, you can choose from either Litespeed or Seven. Those are two great choices!

My carbon favorites are two: the Time VX-SR and the Trek OCLV. The Time is truly a European exotic - the absolute finest that money can buy! If you watched the 2004 Tour de France, this is the bike that Voekler and Virenque rode in the Tour.

Unlike many Look and Orbea models, the Time frames are made in France and not in Taiwan. And the Trek is U.S.-made in Madison, Wisconsin. And it's true: Lance really did race on an out-of-the-box Trek. That's pretty cool.

For those that have ridden the Trek OCLV in the past, you'll have to check out the latest generation - it has finally arrived. I've ridden many of the previous generations, but the latest version is surprisingly good. After test-riding one that I had built for a friend, I told my wife that I'd like to buy one. With their Project One custom program, you can have it custom-painted or custom-assembled with the components you specify.

Other choices? How can you not like the Italian frames from Colnago and Pegoretti? Ernesto Colnago is absolutely, without doubt, the most revered framebuilder in Italy. If you ever travel to the Milan cycling show, you'll quickly know exactly what I mean!

Component group? Campagnolo Record or Shimano Dura Ace. If any shop employee ever criticizes either one of these groups, head for the door! I ridden both for many miles and they are both GREAT! For the life of me, I can't figure out why some shop employees feel the need to criticize one or the other. Campagnolo Chorus or Shimano Ultegra are great choices as well, but not as light or durable.

Pedals are another hot topic of conversation. My attitude is whatever takes care of your knees. I've been a big Time fan ever since Greg LeMond showed me a prototype pair in October of '87. A few years ago, I switched to Speedplay and was thrilled. My wife and I both use Speedplay on our tandem. But recently, I switched back to Time and have been very satisfied.

For several years, I used Time Equipe Pro CX shoes. I really didn't think the shoe brand matters. Fit is far more important and one brand might fit you better than another. But - I just started using the Northwave Aerator Pro Road and I'm totally in love with these shoes! Wow! They are the most comfortable shoes I've worn (and probably the most expensive!).

At any rate, go ahead and buy in the $175 and up range -- they'll last much longer due to the higher quality uppers, straps, and soles.

On the mountain bike side of things, I ride an old Nuke Proof (or Puke Proof as Adam has renamed it!). It's an old Litespeed-made ti equipped with new XT 9-speed and Bontrager wheels. Since I mainly bomb around the trails with my son, I don't feel the need for the latest and greatest - although the Trek and Giant full-suspension bikes are very tempting!

In closing, we sell high-end frames from Waterford, Seven, Litespeed, Merckx, Time, Colnago, Pegoretti, Giant, and Trek. And as we often tell people, we sell what we love - not the other way around. We pick lines that we believe in, not lines that just happen to be available or are the hot frame of the season.

If you have specific questions or need advice, please feel free to call. We're happy to help!

輪組知識

通常許多使用者會測試花鼓順暢度的問題.將輪子做旋轉動作,看看軸承花鼓順度的考驗可以維持多久的運轉.但是不能成為實際騎乘運轉的標準,因為有附載車重與 騎乘者重量下會不相同.舉例來說,一般徑向間隙越大的軸承空轉越順暢,也就轉的越久,徑向間隙越小的就越緊還會感覺的到潤滑油脂的黏膜強度,這就是所謂的高級 高速軸承.高精密度軸承可以做較高的重負載,還可以保持順暢度.包含軸向動作的順暢度(如單車轉向過彎的軸承負載狀態)

後輪傳動側鋼絲2交叉,非傳動側直拉,是為了增加傳動側強度
